Dominion Resources has proposed building a 42 inch natural gas pipeline which, if built as currently proposed, would cross Blue Ridge Parkway near mile 4, and cross the AT in the vicinity of the Paul Wolfe Shelter. There is a web page friendsofnelson.com where you can access maps of the route,see photos of what construction of a pipeline of that size looks like, and read more about the project. I spent the night at Paul Wolfe a week ago, and like it just the way it is.
